Adding form fields before submit is clicked?

lanctotd · July 13th, 2003, 08:37 PM

I have multiple fields that need to be added while the user is entering data, but all I get is the numbers displayed side by side:

strFormName = Request("FormName")
strSubject = Request("subject")
strSendTo = Request("SendTo")
strNumber = Request("txtNumber")
intSize2 = Request("Size2")
intSize3 = Request("Size3")

total = intSize2 + intSize3

any ideas?

Not sure what you mean, because your subject says "before submit is clicked", which sounds like a client side issue and your code shows server side ASP.

Are you referring to the fact that the numbers are not added, but appended? That 2 + 2 equals 22 instead of 4?
If that's the case, convert your numbers to a "real" number data type, like a Int or a Double:

Code:

total = CInt(intSize2) + CInt(intSize3)

If this is not what you're after, please be more specific.

Cheers,

Now the problem I have is if there is nothing in the field it causes a page fault, how can I have it look and see if there is a numnber, if not replace it with a zero?

Thanks

Hi Dan,

You can check the length of the variable's value like this:

Code:

total = intSize2 + intSize3
If Len(total) = 0 Then
    total = 0
Else
    ' Convert it to a Integer
    total = CInt(total)
End If

Cheers,
